To all whom it may concern:

Be it known. that 1, JOHN F. OCoNNoR, a citizen of the United States,siding in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Draft-Rigging for Railway-Cars,.of which the foilowingis a specification.

My invention relates to improvements in draft rigging for railway cars,and more particularly to the construction of the side plates orstopcastings which are secured to are ordinarily made of malleable iron, and

an improved construction of on account of the great length andconsiderable size of the castings and their somewhat irregular shape,due to the necessity of furnishing them with inwardly projectingshoulders forthe followers to abut against onone face, great difficultyis an perienced in practically producing them free from casting strainsor other weaknesses,

,which cause them to. inadequately withstand the enormous strains,,shocks and blows to which they-are subjected in practical operationfrom the draw-bar of the car coupler. The object of'my invention is toprovide draft rigging side late or stop casting, by means of which theiflicultiesor weaknesses heretofore experienced may be practicallyovercome.

My invention consists in the novel construction of draft rigging sideplate or stop casting herein shown and described and more particularly.specified in the claim.

In the accompanying drawing forming a part of this specification, Figure1 is a plan view partly in horizontal section of a draft rigging havinga side plate or stop casting embodying my invention. Fig. 2 is a sideelevation o aside plateor stop casting of my invention, showlng theinside face of the same. Fig. 3 isan elevation, showing the rear face ofthe same-which fits against the side sill or draft timber or memberofthe car frame. Figs. 4 to 8 are cross sections on lines 44, 5P5, 6-6,7-7 and 88 respectively of Fig.3 and Fig. 9 is a longitudinal section online 99 of Fig. 2.

In said drawing, A represents the center sills, draft timbers or framemembers ofa car to which the side plates or stop castings Specificationof Letters Patent. Application filed may 2!), 1908.

the

with transverse bends'or convolu-' lntermediate bend 6 at its'middle toform the two middle steps or shoulders 7, 7 for the two intermedlatefollowers to abut against, and provided also with inwardly projectingrectangular'bosses 8, 8 to form the supplemental stops or shoulders 9, 9which limit the movement of the followers and the compression of thesprings, said rectangular bosses 8', 8, having also longitudinallyextending shoulders This construction leaves the side-plates or stopcastings D with flat smooth wearin faces 11, 11 for the endsof thefollowers to engage, surrounding the raised bosses 8, 8, and between thefront and rear stops 4, 4 and the middle or intermediate stops 7, 7Andto distribute the metal of the side plate or sto casting D so as togive the casting as a who e great strength against bucklin and at thesame time enable the casting to be practically produced free fromcasting strains or other weaknesses, I provide it on its "back face witha series of longitudi- ,.nally extending end recesses 12, 12, havingrounded ends 13 and intervening and mar ginal longitudinally extendingribs 14, 14, and a series of longitudinally extending intermediaterecesses 15, 15 having rounded v marginal ribs 17. The two upperlongitudinally extend- 'ing end recesses 12 have transversely elongateddeepened portions 18, the deepened portions 18 being separated by thenarrowed portion 19 of one of the ribs 14. The lower recess 12 at eachend has no deepened enlargement 18 communicating therewith. The twoupper longitudinally extending recesses or depressions 15 have deepenedpornarrowed portion 21 ofy-the rib 17. The transversely extendingcavities or recesses 22 in the back face of they side plate or stopcasting D formed by the inwardly projecting bosses 8 on the front faceofthe casting are bridged by centralwebs 23,. furnished'w th bolt holes 24to receive the bolts d by which the side plate or stop castings D aresecured to the center sills, draft timbers or other frame members of thecar.

As the recesses or the back of the side )late or stop casting D extendlongitudinal y and have rounded ends 13, although the recesses 12, 12,12,15,

15,, 15 are contiguous to each other. they tensile or in the directionof'its length;

I claim o p In a draft rigging, a side plate stop casting having 4 onits inner face front, rear, intermediate and supplemental stops for thedepressions 12, 15 in followers to abut against, and consisting of amain web 1, furnished with transverse bends or convolutions 4, 4, 6, toform said stops, and inwardly projecting rectangular bosses 8, -8 toform the supplemental stops, and having, a smooth flat bearing face 11between the stop shoulders for the ends of the followers towear against,said stop:

casting having on its back orrear face a series of longitudinallyextending end recesses-or' depressions with ribs between the same and aseries of longitudinallyextending intermediate recesses withlongitudinal ribs between same, said longitudinally extending recessesor depressions on the back face of said stop casting having roundedends, the upper longitudinally extending end and intermediate recessesor depressions. on

the back face of the casting having deepened portions 18, 18 and 20formed by said bends or convolutions 4, 4 and 6, substantially as JOHNF. OGONNOR.
